Sunderland boss Keane raps Allardyce's "percentage football"

He said: "He plays percentage football, plays in your half and makes it hard for you. He had an element of success at Bolton playing that way. People should not be critical of Sam Allardyce, far from it, his career has been very good.

"I don't expect them to play it around at the back. They will be looking to put us under constant pressure and, if we want to win, we will have to defend well.

"He has certainly earned the right to manage a big club. We are all different. There is a way I want our team to play, but certain days it is different horses for different courses. The managers I played for have certain principles on the way the game should be played and that has rubbed off on me."
